18 Claims. '(CL 101-350) My invention is designed to be used in printing spots of wax carbon compoundon sheets of paper such as is described in my Patent No. 1,860,957, issued May 31, 1932. As explained in that patent the regular construction of a press will not serve the purpose, for standard presses generally rely upon the tack of the printers ink to rotate the various rollers but inasmuch as melted wax carbon compound has absolutely no tack, such presses will not function when that compound is used, consequently special construction must be provided to obtain a satisfactory result.

My invention has for its principal object to provide a construction for a standard sheet fed rotary press which will permit the press to be used to print with melted wax carbon compound.

Other objects will appear from the hereinafter contained description.

My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings which are hereunto annexed and are a partof this speci fication, in which- I Fig. 1 is a side elevation of the press from the operators side; 7

In the following specification, I shall conflne my description to the parts I have added to the standard press, the remainder being so well known to those familiar to the art as to render such description superfluous. 1

As shown in the drawings, the press which comprises a feed end 1 and a printing end 2, is equipped with an ink fountain 3 which is heated by electric heating elements 4. An ink fountain roller 5 heated by an electric heating element is mounted in the ink fountain. A large steel vibrating inking cylinder 6 is carried by the shaft 7 which is rotatably and slidably journalled in the side walls A and B of the press.

A ductor roller 8 is mounted intermediate the ink fountain roller 5 and the vibrator cylinder 6,

' suitable linkage 12' is provided to move the ductor roller 9 and two form inking rollers, 10 and 11 mounted to contact the vibrator roller 6. They are preferably formed of a composition which will withstand approximately 200 degrees F. of heat. The distributing roller 9 is driven primarily by sprockets and chain mounted on one side of the press. This driving mechanism consists of an electric motor 13 which drives a pulley mounted upon a shaft 61, and a sprocket 60 carried by the shaft 61. A chain 62 connects the sprocket 60 to sprocket 63 mounted on shaft 38 of the plate cylinder 46. Inside of the sprocket 63 is mounted a sprocket 64 for driving the ink fountain roller 5. This sprocket carries a chain 65 which drives sprocket 66 mounted on shaft 67 of the ink fountain roller 5. In this manner the ink fountain roller 5 is positively driven. The distribution roller 9 is also driven from the shaft 38 by means of a chain 68 and sprockets 69 and '70 mounted on shaft 38 and 16 respectively. At one end of the roller 9 and between it and the side frame A of the press, I provide two sprockets 14 and 15- mounted on shafts 7 of the vibrator cylinder, and shaft 16 of the distributing roller 9 respectively these sprockets carry a chain 13. At the other end of the roller 9 on shaft 16 intermediate the side B of the press and the end of the roller 9, I mount a sprocket 1'! as clearly seen in Figs. 3,

- 24 and 26, this carries a chain 18 which extends around sprockets 19 and 20 mounted on the shafts 21 and 22 of the form inking rollers 10 and 11, the result being that these rollers are positively driven all the time the press is running. The sprockets 1'7, 19 and 20 are preferably mounted inside the press as clearly seen in Figs. 3 and 24, while the sprockets 14 and 15 are mounted at the opposite side of the press but inside of the side frame A of the press.

The shaft '1 carrying the vibrator roller 6 is reciprocated longitudinally by means of a gear 22 which is mounted upon a shaft 50 carried by a journal 51 which is suitably bolted to the slde'of the press, meshing with a pinion 23 fixedly mounted on the end of shaft 7 in the usual manner. This longitudinal movement of the shaft 7 would naturally carry with it the sprocket 14 and cause it to be moved out of alinement with the sprocket 15. I overcome this by splining the sprocket 14 on shaft 7 and then making a strap 24 which fits around shaft 7 and is bolted to the side wall of the press thus holding the sprocket 14 in line with the sprocket 15. regardless of the reciprocation of' shaft '1. This construction is clearly shown in Figs. 27 and 28. The-vibrating roller 6 is heated by means' of an electric heating element 12. The electric conductors 24' and 25 are carried through the shaft 7, which is made hollow at. that end for that purpose, and are connected to collector rings 26 and 27.

These rings are contacted by brushes 28 and 29 which are held against the collector rings by means of coil springs 30. The springs are located of the vibrator roller 6 moves longitudinally, it is necessary to provide means for mounting the .con-

ductors to move with the shaft. I accomplish thisby mounting the brush holder in a carriage 33, which is slldably mounted upon the end of the 1,ass,ssa

shaft 16 which projects out beyond the side A of the press and forms a guide shaft for the carriage 33. Obviously when the shaft '1 is reciprocated longitudinally, the collector rings will move with it, this movement will cause the carriage 33 to slide back and forth on the guide shaft 34 carrying with it the brushes 28 and 29 thus maintaining contact at all time. The brushes 28 and 29 areeonnected by means of suitable electric conductors 35 and 36 to a source of electric current supply (not shown). It will be seen that these conductors must be flexible to permit the movement-oi the carriage 33 without interfering with the flow of current.

The 'plate cylinder 46 is so large that it cannot, with a single element, be maintained at the critical temperature so essential to the printing of spots of wax carbon compound so I employ a plurality of such elements 4'7. As illustrated they are three in number which are carried by spiders 47' which are fixedly mounted :upon the shaft '7 for that purpose though obviously any suitable means of mounting the heating element may be employed as desired. One end 37 of the shaft 38 for the plate cylinder 46 is made hollow and the electric conductors 39 are led through it to collector rings 40 and 41 suitably mounted upon end 37 of shaft 38. This construction is clearly shown in Figs. 10 to 14 inclusive.

A chain and sprocket guard 42 is.provided on the operator's side B of the press, this being the operators side to protect the operator from accidental contact with the driving meansnwhich has heretofore been described.

As explained in my Patent No. 1,961,829, the standard means of controlling the temperature of the heating elementsis not suiilciently sensitive and it is necessary to provide auxiliary or supplemental heat controls 55, 55' and 55" which are mounted adjacent the vibrator roller, the plate is placed inthe ink fountain 3 in which it is melted. Current is then turned on to the motor 13 and this drives the press, and as explained the ink fountain roller 5, the ductor roller 8, the vibrator roller 6 and the distributing roller 9 and the form inking rollers, 10 and 11 are all 'positively rotated through the driving mechanism previously described. The sheets of paper (not shown) pass from the automatic sheet feeder 1 over the sheet feed conveyor 44 to the plate cylinder 46 passing between it and the impression cylinder 44, they have the spots of wax carbon printed on them, they then pass on to delivery table where they are stacked in the usual manner.
